| ## <a id="topic1__section3"></a>Description |
| |
| `SELECT INTO` creates a new table and fills it with data computed by a query. The data is not returned to the client, as it is with a normal `SELECT`. The new table's columns have the names and data types associated with the output columns of the `SELECT`. Data is always distributed randomly. |
| |
| ## <a id="topic1__section4"></a>Parameters |
| |
| The majority of parameters for `SELECT INTO` are the same as [SELECT](SELECT.html). |
| |
| <dt>TEMPORARY, |
| TEMP </dt> |
| <dd>If specified, the table is created as a temporary table.</dd> |
| |
| <dt> \<new\_table\> </dt> |
| <dd>The name (optionally schema-qualified) of the table to be created.</dd> |
| |
| ## <a id="topic1__section5"></a>Examples |
| |
| Create a new table `films_recent` consisting of only recent entries from the table `films`: |
| |
| ``` sql |
| SELECT * INTO films_recent FROM films WHERE date_prod >= |
| '2006-01-01'; |
| ``` |
| |
| ## <a id="topic1__section6"></a>Compatibility |
| |
| The SQL standard uses `SELECT INTO` to represent selecting values into scalar variables of a host program, rather than creating a new table. The HAWQ usage of `SELECT INTO` to represent table creation is historical. It is best to use [CREATE TABLE AS](CREATE-TABLE-AS.html) for this purpose in new applications. |
